Heterogeneous catalyzed reduction of polymer-bound nitroarenes
Deposition of palladium as a catalyst on polymer beads, such as Merrifield resin or TentaGel, allows the reduction of polymer-bound 4-nitro benzoate to the corresponding anilines with dilute hydrazine hydrate solution in DMF at room temperature.
